The transition directive
We can make more appealing user interfaces by gracefully transitioning elements into and out of the DOM. Svelte makes this very easy with the transition
directive.
First, import the fade
function from svelte/transition
…
<script>
import { fade } from 'svelte/transition';
let visible = true;
</script>
…then add it to the <p>
element:
<p transition:fade>Fades in and out</p>
